[漢羅] 九月 ê 日出烏影

2022 年 9 月 23 拜五 世界協調時 1:03，是太陽 tī 地球天頂路線 kah 天球赤道交叉，向南方行去 ê 時陣。 天文上就是按呢咧定義 逐年 九月 ê 春秋分點。 這个時陣開始，tùi 咱這个 美麗地球 ê 北半球來講就是秋天，tùi 南半球來講就是春天。 這工 ê 日時 kah 暗暝差不多是平長。 是講，你若是欲慶祝 天文定義 ê 換季，你會當欣賞日出，嘛會當欣賞這个佛光。 這个雲造成 ê 烏影投影，會 tī 日出抑是日落、晨昏交界 ê 時陣，產生戲劇性 ê 景色。 因為透視效應，平行 ê 烏影敢若是 ùi 日出 ê 方向射過來--ê。 這工閣是 tī 春秋分點前後，所以 遐 就 tī 地平線 正東 ê 方向。 這張相片是 9 月 15 這工 tī 意大利 Petacciato 庄頭附近 ê 地中海海岸翕--ê。 有翕著日出這陣 ê 天景 kah 海景，包括天頂 ê 佛光 kah 海面 ê 反射。

[English] September Sunrise Shadows

The defining astronomical moment for this September's equinox was on Friday, September 23, 2022 at 01:03 UTC, when the Sun crossed the celestial equator moving south in its yearly journey through planet Earth's sky. That marked the beginning of fall for our fair planet in the northern hemisphere and spring in the southern hemisphere, when day and night are nearly equal around the globe. Of course, if you celebrate the astronomical change of seasons by watching a sunrise you can also look for crepuscular rays. The shadows cast by clouds can have a dramatic appearance in the twilight sky during any sunrise or sunset. Due to perspective, the parallel shadows will seem to point back to the rising Sun and a place due east on your horizon near the equinox date. Taken on September 15, this sunrise sea and skyscape captured crepuscular rays in the sky and watery specular reflections from the Mediterranean coast near the village of Petacciato, Italy.
